May have bricked my phone need help!

Was trying to revert my phone to stock b.c all the Charge roms pretty much suck as much as this phone does and all it ever did was FAIL on Odin. Thats not the issue though. I pick up my phone today after where I left it and now after holding down the volume down button and connecting USB it wont even go into download mode. Tried plugging it into the wall nothing happened. Phone wont turn on either. Help!
